Hawthorn belongs to the genus Crataegus, which encompasses several hundred species of shrubs and trees native to temperate regions of the Northern Hemisphere in Europe, Asia, North Africa, and North America 11. These hardy plants are characterized by their thorny branches, five-petaled white flowers, and distinctive berry-like fruits that range in color from yellow to deep red and black.
The most commonly studied and utilized species include:
- Crataegus monogyna (Common hawthorn) - predominant in Northern Europe
- Crataegus laevigata (Midland hawthorn) - found in Middle Europe
- Crataegus pinnatifida (Chinese hawthorn) - widely cultivated in Asia
- Crataegus mexicana (Mexican hawthorn) - native to Central America
Proven Health Benefits of Hawthorn
1. Cardiovascular Protection and Heart Health
Hawthorn's most well-documented benefit lies in its remarkable cardiovascular protective properties. Research has demonstrated that hawthorn could be used as an alternative therapy for various cardiovascular diseases, including angina, hypertension, hyperlipidemia, arrhythmia, and New York Heart Association (NYHA) functional class II congestive heart failure 21.
Key Cardiovascular Benefits:
- Blood Pressure Reduction: A systematic review found that hawthorn can significantly lower blood pressure in people with mild hypertension if applied for at least 12 weeks 28
- Cholesterol Management: Studies show hawthorn extract can improve blood lipid profiles by reducing total cholesterol and triglyceride levels
- Enhanced Circulation: Hawthorn acts as a natural vasodilator, helping to relax constricted blood vessels 2
2. Powerful Antioxidant Properties
Hawthorn berries are rich in polyphenols, powerful antioxidant compounds that neutralize harmful free radicals in the body 2. These antioxidants provide multiple health benefits, including the ability to prevent and reduce the risk of asthma, infections, type 2 diabetes, premature skin aging, cancer, and heart problems.
Recent research highlights hawthorn's multifaceted bioactivities, including antioxidant, anti-inflammatory, anticancer, antidiabetic, and antiviral properties 4.
3. Anti-Inflammatory Effects
Chronic inflammation is a major contributor to various diseases, including asthma, type 2 diabetes, and certain cancers. Animal studies have demonstrated that consuming hawthorn fruit extract can significantly reduce inflammatory compound levels in the body, contributing to reduced inflammation and asthma symptoms 2.
4. Digestive Health Support
Hawthorn has been extensively used in traditional medicine to aid digestive problems, particularly stomachaches and indigestion. The berries contain significant amounts of fiber, which helps support the digestive system by reducing constipation and acting as a prebiotic 2, promoting the growth of beneficial gut bacteria.
Research shows that hawthorn extract can significantly accelerate food transit through the digestive system, reducing indigestion and providing stomach protection similar to anti-ulcer medications 2.
5. Blood Sugar Management
Studies have reported that 80% methanol extracts of hawthorn were able to reduce blood glucose levels and increase insulin sensitivity 5. Various research has shown that Crataegus pinnatifida can have beneficial effects on controlling and treating high blood sugar, dyslipidemia, and obesity 23.
6. Skin Health Benefits
Recent research has explored hawthorn's effects on facial skin health. A randomized, double-blind, placebo-controlled intervention study aimed to evaluate whether hawthorn fruit supplementation can influence facial skin appearance and health 6, suggesting potential anti-aging properties.
